NGAF hacker prevention feautures

Hi,
What would be the best solution to prevent from hacker to obtain the server information

The FTP Server often return to server version information.Hacker may take advantage of this to seaarch for server vulnerablities.Which of the function in NGAF can prevent hacker to obtain the server information?

1.FTP Weak Password Protection
2.Application hiding
3.Website Scan
4.File Upload Restriction

The best solution would be to utilize the "Application hiding" function in Next-Generation Firewall (NGAF). This feature allows the firewall to disguise or obfuscate specific application signatures or characteristics, thereby concealing information about the server's FTP version. By hiding this information, potential attackers are thwarted in their attempts to identify vulnerabilities based on server version details, effectively mitigating the risk of exploitation.

Sangfor NGAF offers a couple of functionalities that can help prevent hackers from obtaining server information through FTP:

    Web Application Firewall (WAF): The WAF can be configured to mask server version information in the HTTP response headers. This stops hackers from identifying the specific server software and exploiting known vulnerabilities.

    Intrusion Detection System (IDS): The IDS can be configured to detect and block attempts to exploit known vulnerabilities in FTP servers. This helps prevent hackers from gaining unauthorized access to the server and its data.

By combining these Sangfor NGAF features, you can significantly improve your server's security posture against attacks that try to exploit server vulnerabilities exposed through FTP.

My suggestion, you can consider the solutions:
1) Protection Against Weak FTP Passwords to protect against brute force attacks
2) Hiding the application to protect information about the server from being sniffed by attackers

Hi,
"Application hiding" is the way. Use it on NGAF.

Using Application Hiding in your NGAF solution is the best option to prevent hackers from obtaining server information through FTP. However, it is also crucial to implement other security measures to ensure the overall security of your FTP server and network.

The best solution to prevent hackers from obtaining server information through FTP would be "Application Hiding." This function is part of Next-Generation Firewall (NGAF) solutions, which helps in hiding the server version details from potential attackers.

Application Hiding, also known as Server Signature or Server Masking, works by modifying the server's response to hide the server's version and other identifying information. This makes it more difficult for hackers to identify and exploit vulnerabilities specific to your server version.

While other options like FTP Weak Password Protection, Website Scan, and File Upload Restriction can also contribute to securing your FTP server, they do not directly address the issue of hiding server information.

Hi, Sangfor’s NGAF is a converged security solution providing protection against advanced threats, malware, viruses, ransomware, and web-based attacks using integrated security features like Firewall, IPS, AV, Anti-malware, APT, URL filtering, Cloud Sandbox, and Web Application Firewall (WAF).
It’s important to note that securing an FTP server involves several steps, including using secure FTP versions like SFTP or FTPS, strong passwords, firewall configurations, and regularly updating and patching the FTP server software.
About your question, i suggest you to consider there Sangfor NGAF solutions:

1) Protection Against Weak FTP Passwords: This is implemented to counteract brute force attacks.
2) Concealment of Applications (application hiding): This is done to prevent the exposure of the server version or the type of firmware running on the server to the public.

application hiding prevents hackers from seeing the FTP service

Weak Password Protection
application hiding.

To stop hackers from finding out our server's info, like our FTP server version:
"Application hiding" is your best choice.
In Addition, follow this simple plan:
1._Hide banners: Don't let our server spill its version in banners.
2. Change answers: Make our server give vague answers instead of the real deal.
3. Keep it generic: Don't use names or versions that give us away.
4. Stay updated: Keep our FTP software up-to-date to fix any weak spots.

By hiding what our server is, we make it tough for hackers to know what to attack. But don't forget other safety steps too!
